How it works

Pick a date and time, choose the time zone it's in and the time zone to convert to, and get an instant result. Time zone data -- including exactly when daylight saving starts and ends in each zone -- comes entirely from your browser's built-in Intl API, so results stay correct even right around a daylight saving transition. Nothing here relies on a fixed, hard-coded offset.

Does this handle daylight saving time correctly?

Yes. Conversions use your browser's built-in time zone data for the exact date you choose, so daylight saving transitions in either time zone are automatically accounted for -- nothing is based on a fixed offset.

Is my chosen date, time or location sent anywhere?

No. All conversions happen entirely in your browser. Analytics only records that the tool was used, never the date, time or time zones you choose.
